Abstract:
A display apparatus includes a matrix of light emitting elements, a plurality of drive circuits provided for driving the light emitting elements, a plurality of scanning lines to which a scanning signal is applied to select the drive circuits on a row basis, a plurality of control lines to which a light-emission control signal is applied to determine an emission period of the light emitting elements, and a plurality of data lines to which image signals are applied to define brightness of the light emitting elements on a column basis. The scanning signal is sequentially applied to the scanning lines in a field so that the image signals of the data lines are programmed in the drive circuits, and the light-emission control signal is sequentially applied to the control lines to make the light emitting elements emit light with brightness corresponding to the image signal programmed to the drive circuit. An impulse operation, constituted by a high level and a low level of the light-emission control signal, corresponds to on and off of the light emission element, respectively, and is repeated at least twice in different temporal patterns in a period from programming of the image signal necessary for display of one image to inputting of the next image signal.
